[Spasmus nutans. A re-emergent pathology?]

Abstract

The authors report two cases of spasmus nutans (a clinical syndrome peculiar to infancy the complete form of which is characterised by nystagmus, rhythmic head movements and wryneck) in two extra-EEC infants. The following elements were present in both patients: scarce exposure to light, early introduction of whole cow's milk, rachitic stigmata, dark skin, poor socio-economic conditions and rapid and complete remission of symptoms following daily exposure to sunlight. It is important to distinguish spasmus nutans, a completely benign and self-restricting disease, from potentially severe conditions which may appear with similar symptoms. It should be expected that this clinical condition will become more frequent in view of the considerable increase in the size of the non-EEC population.
